The "solutions" are fairly straightforward but they're work arounds for sure. 1) If you're going to shut off the engine, empty the ram-fill ballast first. 2) leave the engine running while the boat is slammed.

Basically at rest, the engine on a fully ballasted boat is so low that the exhaust risers are below the water line and when the engine's not running, the water can go from the exhaust outlet up and over the risers and into the block. Yes, it has a flapper, but that doesn't seal watertight so it could slow the backflow but not eliminate it.
Wow interesting. Makes me like the factory surf pipe with the tall bend design. I assume that’s by design to keep water flowing one way only.
